视频播放器
进入公司一个月拉，总于有机会写个视频播放器了，这次的工作内容主要是给视频播放器加上弹幕功能条，可惜是个小前端，主要是提功能接口和json给后台。

后台：

$file = "/tmp/danmu.json";
//$body = @file_get_contents($file);
$msg = $_POST["msg"];
$time = $_POST["time"];
$fontSize = $_POST["fontSize"];
$fontMode = $_POST["fontMode"];

$line = $msg."##".$time."##".$fontSize."##".$fontColor."##".$fontMode."##".$timestamp."\n";
file_put_contents($file,$line,FILE_APPEND)
}
?>
难点所在：由于弹幕功能条以后有可能放进播放盒里面，而不是简单嵌入到html里面，因此尽量少使用图片，所以按钮是css绘制的；
获取弹幕设置的数据。
